American forward Corey Hertzog went on trial with Falkensberg FF of the Swedish Allsvenskan last week but was forced to return home early after suffered a pulled hamstring.

After a college career at Penn State, Hertzog was drafted by the New York Red Bulls with the 13th overall pick in the 2011 MLS SuperDraft. After the 2012 season, he signed with the Vancouver Whitecaps in 2013. Towards the end of the 2013 season he was loaned to lower division club FC Edmonton in Canada.

Last week Falkesnberg, who were just promoted to Sweden's top tier, confirmed the trial to YA but his injury was subsequently confirmed to YA by Arthur Auchenbach who is the president of Pennsylvania-based minor league club Reading United near where Hertzog grew up.

According to Auchenbach, the 23 year old Hertzog will rehab his injury at Reading and more will be known about the severity of his injury this week.

"Corey is now back in Reading for his rehab with Reading United staff," Auchenbach said. "He will be with the doctors tomorrow morning. More known then."
